TUTORIAL 1 WORKSHEET The Whole Brain 1. The brain along with the spinal cord makes up which major division of the nervous system?

Central Nervous System 2. What are the 3 primary brain divisions (these appear early in development as 3 vesicles)?

Prosencephalon (Forebrain), Mesencephalon (midbrain), Rhombencephalon (hindbrain) 3. What do we call the thick band of fibers connecting the two hemispheres?

Pons Medulla oblongata Myelencephalon (hindbrain) Metencephalon (hindbrain) Mesencephalon (Midbrain) 7. Can you name some functions associated with the cerebellum?

Motor control.. coordination, voluntary movement Balance Motor learning 8. Can you name some functions associated with the cerebrum?

Voluntary motor control, Sensory processing, Executive function, Language, Emotion, Memory etc. The Brainstem 1. Can you name some functions associated with the brainstem?

Regulate heart rate, breathing, sleeping, and eating. 2. What are the small structures visible on the medulla?
